I see somebody else mentioned objdump in the GNU binutils package. A
more specific ecoff dumper that knows about the line number format and
such is the program mips-tdump, which is inside the GCC (GNU Compiler)
package that I wrote a couple of years ago so that I could write
mips-tfile, which allows the GNU C compiler to insert debug
information into object files produced by the MIPS assembler (which
provided no way of third party compilers from creating debug
information other than line numbers). I haven't worked on mips-tdump
in a couple of years, though.....
